1. DNA stands for Deoxyribonucleic Acid.
2. The monomer of DNA is called a nucleotide.
3. The three molecules that make up a nucleotide are a sugar (deoxyribose), a phosphate group, and a nitrogenous base.
4. The two molecules that make up the "backbone" of the DNA molecule are the sugar (deoxyribose) and the phosphate group.
5. The four different bases are adenine, thymine, cytosine, and guanine.
6. Purines have two ring(s) in their structure, and pyrimidines have one ring(s) in their structure.
7. The two bases that are purines are adenine and guanine. These bases are comprised of two rings.
8. The two bases that are pyrimidines are thymine and cytosine. These bases are comprised of one ring.
9. Based on this information, scientists could predict that the base adenine pairs with thymine and the base cytosine pairs with guanine in the formation of the DNA molecule.
